The GEI may be interpreted as an estirnate of <strong>the</strong> acid neutralizing capacity of <strong>till</strong> (cf. de Vries & Breeuwsma 1987). The accelerated cation leaching induced by increased H+ input in precipitation may lead to cation nutrient shortage being faster on soils with low GEI than on o<strong>the</strong>r soils. But <strong>the</strong> mechanism of <strong>the</strong> possible influence of <strong>till</strong> <strong>geochemistry</strong> on <strong>the</strong> <strong>occurrence</strong> of scleroderris canker remains to be studied.
